Ah, I see. This is not as clear-cut as it might seem, worldwide. There are
many laws on the books about marked crossings that are not directly
superceded by the existence of signals. It can get pretty complex: it may
be illegal (and sometimes dangerous) for a pedestrian to enter an
intersection under a "do not walk" signal, but the law can still imply
virtually all of the crosswalk statutes, including that drivers must still
yield when that pedestrian breaks the law.

One option is to just explicitly tag right of way on every crossing, but I
wouldn't ever actually help with that and I'm not entirely certain that the
data would even be useful. That seems like something better left to data
consumers, who can just know the laws for a region being serviced. If it's
really necessary to tag laws in OpenStreetMap, I'd favor tags on a regional
polygon.

Not saying you were asking for any of those things. I believe it's just the
logical conclusion to "right of way" coming up so frequently.
